The S1W propulsion plant was built at the National Reactor Testing Station near Arco, Idaho.

Under the leadership of Hyman Rickover, Naval Reactors followed a concurrent design strategy, overseeing the design and construction of the S1Wreactor ahead of the design and construction of the Nautilus, enabling problems to be identified and resolved in the shipboard plant.

United States Naval reactors are given three-character designations consisting of a letter representing the ship type the reactor is designed for, a consecutive generation number, and a letter indicating the reactor's designer.

After the Skate-class vessels, reactor development proceeded and in the USA a single series of standardised designs was built by both Westinghouse and General Electric, one reactor powering each vessel.

A marine reactor was used to supply power (1.5 MWe) to a US Antarctic base for ten years to 1972, testing the feasibility of such air-portable units for remote locations.

Reactors are sited, designed, constructed, modified, operated, maintained, and decommissioned in a manner that gives adequate protection for health and safety and will be in accordance with uniform standards, guides, and codes which are consistent with those applied to comparable licensed reactors.

Reactor Facility, unless it is modified by words such as containment, vessel, or core, means the entire reactor facility including the housing, equipment, and associated areas devoted to the operation and maintenance of one or more reactor cores.

Reactor Operations are all those activities or functions involved in operating and using a reactor which, for purposes of this Order, begin with the initial loading of fuel in the reactor vessel and end with the removal of fuel to officially decommission or place the reactor in a standby status.

A nuclear reactor is a device in which nuclear chain reactions are initiated, controlled, and sustained at a steady rate (as opposed to a nuclear explosion, where the chain reaction occurs in a split second).

Critical fission reactors usually consist of several parts: a reactor core that houses the reaction itself; a working fluid (usually water) to remove heat from the reactor core; some sort of shielding to prevent the reactor from emitting ionizing radiation and neutrons; and a containment vessel to prevent leakage of radioactive isotopes.

In many reactors, the rods are mounted vertically and suspended by electromagnets, so that interrupting the power to the electromagnets causes the reactor to fail safely by dropping all of the rods into the core.

Each propulsion plant is capable of operating on one reactor plant through most of the power range required to propel the ship (at speeds in excess of 33 knots (61 km/h) - rumours of speeds of 60 knots (111 km/h) are just that - rumours).

There the heat from the reactor coolant water is transferred, through tube walls, to water being fed into the steam generators from a separate feed system.

Once the reactor coolant water has given off its heat in the steam generators, it is returned, via large electric pumps (four per reactor), to the reactors to repeat the cycle.

Under the leadership of Hyman Rickover (Hyman Rickover: United States admiral who advocated the development of nuclear submarines (1900-1986)), Naval Reactors followed a concurrent design strategy, overseeing the design and construction of the S1Wreactor ahead of the design and construction of the Nautilus, enabling problems to be identified and resolved in the shipboard plant.

For submarines, the reactor compartment is a horizontal cyhder formed by a section of the ship’s pressure hull, with shielded bulkheads on each end.

Reactor coolant carries some of these radioactive products through the piping systems where a portion of the radioactivity is removed by a purification system.

The submarine thermal reactor prototype was constructed in 1951 and shut down in 1989; the large ship reactor prototype was constructed in 1958 and shut down in 1994; and the submarinereactor plant prototype was constructed in 1965 and shut down in 1995.

The designation "S1W" can be translated as follows: S - Submarine propulsion plant 1 - The first reactor model by the primary contractor W - Westinghouse, the primary contractor The S1W propulsion plant was built at the National Reactor Testing Station near Arco, Idaho.

On July 17, 1955, reactors at the NRTS made Arco, Idaho, the first town in the world to be powered by atomic energy.

It could be argued that because of Rickover's singular focus on reactor operations, and direct line of communications with each nuclear submarine's captain, that this acted against the captains' warfighting abilities.

Various chemical and radioactive wastes were generated from these three reactors and the support facilities at ANL-W. The operation of these facilities and the corresponding waste streams have been evaluated and documented in the Facility Assessment and Screening document of 1973.

The BORAX-I reactor was intentionally destroyed in 1954 to determine its inherent safety under extreme conditions and afterward was buried in place.

The OMRE was a nuclear reactor that operated from 1957 to 1963 approximately 3.25 km (2 mi) southeast of the Central Facilities Area (CFA) and included a leach pond used for wastewater disposal from the reactor.

The U.S. Army operated a small reactor out in the Idaho desert (at the National Reactor Testing Station) that was intended to be used for powering remote radar stations to be used in the early warning system.

For various reasons, there was an accident that claimed the lives of all three technicians, required the complete disassembly of the plant and in many good ways, significantly influenced the way that military nuclear facilities were operated.

None of this is stopping INEEL from doing new research and development on Generation IV reactors as the DOE puts it.

This is an ACRS concern raised by the Subcommittee on TMI-2 Implications in October 1979.

This issue centers around the possibility of a breach in the reactor coolant system boundary caused by the failure of nonsafety interlocks between pressurizer water level and pressurizer heater power and prolonged overheating of the immersion heaters due to operator failure to detect and terminate electrical power.

The obvious solution would be to upgrade and expand the heater power and pressurizer level interlocks, operator training, and control of IandC modifications and repair efforts in accordance with QA procedures for protective systems rather than normal nonsafety plant systems.

--------------------------------------------------------------------------- The Employer operates the Naval Reactor Facility (NRF) for the U.S. Department of Energy and the U.S. Navy.\4\ The NRF, located on a 75-acre government preserve, operates nuclear reactor plants and a material handling facility.

The NRF also operates three prototype nuclear reactor plants: Aircraft Carrier 1 Westinghouse (A1W), Submarine Fifth Generation (S5G), and Submarine First Generation Westinghouse (S1W).\5\ The prototype reactor plants are used to train civilian and Navy personnel and to test machinery.

In 1962, the Board in refusing to exclude industrial hygienists from an appropriate unit observed: Their main function is to check on contamination levels in the different facilities, and to prescribe interim correction of hazardous conditions, and the proper repair of defective equipment.

The S1W prototype they built for the Nautilus was just one of many reactors at the site.

Probably the most infamous of the NRTS reactors was the SL-1, which blew up on January 3, 1961.

On the film badges we wore to measure the amount of radiation we had received every month there was a tiny metal canister, the purpose of which was to measure the amount of radiation our dead bodies would have received in the event of another SL-1 type accident.

At INEEL, DOE refuses to build such a repository because the Department is not being pressured by the state and EPA regulators to comply with the law.

It is possible that the earlier sampling grid identified hot spots that the later sampling grids could be planned to avoid.

These high contamination levels were due primarily to once through reactor cooling water dumped in the leach pits which was discontinued by 1980.

Following the completion of the six-month theoretical portion of the nuclear submarine training program he attended the six-month practical engineering training program at the S1W prototype for the USS Nautilus (the first nuclear submarine) and qualified as Engineering Officer of the Watch.

Division Officer and the Start-up Reactor Physics Program Coordinator for the ship and also qualified as Engineering Officer of the Watch on the S5W submarinereactor plant.

He became the Plant Engineering Manager, qualified as Shift Technical Advisor, and was certified as a Senior Reactor Operator and also served as a member of the Plant Review Board responsible for ensuring nuclear safety oversight for plant operations.

He has over 25 years experience in materials, metallurgical, and corrosion engineering in the areas of stainless and nickel based alloy development, corrosion and aging testing of metallic and non metallic materials, welding engineering, application of non destructive examination techniques to characterize new and aged engineering structures and lifetime prediction of materials in specific services.

He is presently the technical lead for the development of a nickel-based, gadolinium-containing alloy that will be used as a fixed neutron absorber for storage of DOE spent nuclear fuel.

Since arriving at the INEEL in 1984 she has worked on projects varying from mining metals recovery to bio-corrosion and aging of reactor components.

It is listed that The 98S1W Molten Orange is the only bike to come with nuke blue frame and wheels now that might not be totally true IE you can always change body work and wheels but from the factory, that was what was stated.

The 98S1W was available in four frame colors and four body colors...mixed in all four combos.

Hey Spidey, you forgot about the 98 S1W Liberace edition thet we discussed on another board.
